JES2 Spool data set consists of SYSOUT + JCL source + SYSIN data + JCL contol blocks. JES2 analyze and groups job outputs for output class,route code,priority, Etc.

If we are referring to the JES2 output of a single job — this is SPOOL data, not a data set that can be accessed in any normal way. There is no data set name assigned to a spool file.

When JES2 is started during IPL it uses members SYS1.PARMLIB(JES2CMDS)

and SYS1.PARMLIB(JES2PARM) defining some important spool parameters:

JOBCLASS(A-Z) AUTH=ALL, /* All commands accepted */

LOG=YES, /* Print JES2 JOB LOG */

OUTDISP=(HOLD,HOLD), /* Disposition of System Output */

/* normal termination and abnormal */

OUTPUT=YES, /* Produce Output for Job */

SPOOLDEF

BUFSIZE=3856, /* MAXIMUM BUFFER SIZE &BUFSIZE */

DSNAME=SYS1.HASPACE,

FENCE=NO, /* Don’t Force to Min.Vol. &FENCE */

SPOOLNUM=32, /* Max. Num. Spool Vols */

TGBPERVL=5, /* Track Groups per volume in BLOB */

TGSIZE=33, /* 30 BUFFERS/TRACK GROUP &TGSIZE */

TGSPACE=(MAX=195456, /* Fits TGMs into 4K Page &NUMTG=(, */

WARN=80), /* &NUMTG=(,% */

TRKCELL=5, /* 5 Buffers/Track-cell &TCELSIZ */

/* No. of Devices (units) UNITCT */

JES2 spool data are including:

SYSIN and SYSOUT data sets
JESNEWS
Trace data sets
SYSLOG
Spool offload data

During job execution, JES2 creates data sets for a job’s input (SYSIN) and output (SYSOUT).

These data sets might exist after the job completes execution.

In a job we get output data sets with the following DDNAME: JESMSGLG, JESJCL, JESYSMSG, SYSPRINT, SYSOUT, CEEDUMP etc.

What is the max size of that SYSOUT?

The maximum size of a job in the spool is equal to the unused available space defined to the JES2 spool dataset. The only standard datasets (always present for JOB/STC/TSU ) are JESMSGLG, JESJCL, JESYSMSG and all the other names are optional, user defined. The maximum size/number_of_records for a spooled dataset ( print/punch ) is determined by the spool capacity and the rules imposed by JES2 customization.

Example of JES2 data for CICS application system when in z/os TSO/ISPF– sd.st – you entered the follwing – ? BC2AC10A:

DDNAME StepName ProcStep DSID Owner C Dest Rec-Cnt

JESMSGLG JES2 2 BC2AC10A X 2,003

JESJCL JES2 3 BC2AC10A X 138

JESYSMSG JES2 4 BC2AC10A X 2,464

DFHCXRF BC2AC10A 101 BC2AC10A X 0

MSGUSR BC2AC10A 103 BC2AC10A X 28,891

PLIMSG BC2AC10A 104 BC2AC10A X 0

COUT BC2AC10A 105 BC2AC10A X 0

CEEMSG BC2AC10A 106 BC2AC10A X 0

CEEOUT BC2AC10A 107 BC2AC10A X 0

PRINTER BC2AC10A 114 BC2AC10A X 0

CAFF BC2AC10A 115 BC2AC10A X 0

CRPO BC2AC10A 116 BC2AC10A X 0

JESMSGLG – This JES2 output data set is saved in SYSLOG:

The JESMSGLG output data set (which is part of JOB data in JES2) resides on SYSLOG for each job in the system and contains system messages related to the job starting and ending.

JESYSMSG – JES2 system messages output data set is also saved in SYSLOG. It contains all system communications /information messages related to the job.

All other JES2 data (including JESMSGLG and JESYSMSG) are saved in JES2 spool and can be offloaded on save tape for later reload when needed.
